FASTENER.

Specification of Letters Patent.

Patented Apr. 13, 1920.

Application filed October 26. 1918. Serial No. 259.800.

T 0 all whom it may concern Be it known that I, FRED S. CARR, a citizen of the United States, and resident of Newton, in the county of Middlesex, Commonwealth of Massachusetts, (whose postofiice address is care of Carr Fastener Company, Cambridge, Massachusetts,) have invented an Improvement in Fasteners, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to improvements in separable fasteners, and more particularly, though not exclusively, to improvements in separable fasteners wherein a stud having an expansible head cooperates with a socket having a stud-engaging portion of fixed dimensions, and wherein the stud is separable from the socket by tipping movement in one direction only.

This application is in part a renewal or continuation of and in part a substitute for my application Serial No. 21 14,252, filed November 27, 1917, and allowed April 5, 1918.

In the drawings Figure 1 is a front elevation of a preferred form of one embodiment of my invention;

Fig. 2 is a section thereof on the line 2--2 of Fig. 1;

Fig. 3 is a rear elevation of the embodiment of my invention shown in Fig. 1;

Fig. 4 is a top view of a preferred form of resilient jaw for use in connection with my invention; and

Fig. 5 is a side elevation of the aw shown in Fig. 4.

In the preferred form of my invention selected for illustrative purposes, I have shown a socket in the form of a round hole in the side 6 of an automobile. shown a stud secu ed to an automobile curtain T and having a head 8, preferably pressed from a flat plate of metal, and providing on one side thereof an abrupt shoulder 9 for engagement with the side of the socket, and preferably being provided on the opposite side thereof with a resilient expansible element 10 projecting through a slot 11 in the side of the head 8 of the stud, and preferably formed of wire crimped between the base flange 12, the head of the stud and a flange 13, from which there projects a tubular portion 14 adapted to be ex- 1 have panded over and engage a clench plate 15 on the opposite side of the curtain 7, thereby to secure the stud firmly to the curtain and to provide an advantageous form of fastenin for the resilient jaw element.

he jaw element 10 preferably has its outer end contained within the head 8 of the stud in such a way that the looped portion thereof, adapted to engage the opposite side of the socket aperture from the non-resilient abrupt shoulder 9, may resiliently engage the opposite side of the aperture in the socket.

\Vhen it is desired to enter the stud in the socket, the head of the stud is pressed against the aperture in the socket and the resilient element 10 recedes into the head of the stud, thereby permitting the head of the stud to enter the socket, and as soon as the shoulder 9 has passed the inner edge of the socket the spring element 10 will push the head upwardly so that the fixed jaw 9 firmly engages the inside of the socket. At the same time the rounded portion of the spring jaw 10 preferably overlies the opposite side of the aperture in the socket, resisting to some extent any minor forces exerted to remove the stud from the socket. The base flange 12 and the flange 13 are preferably, as shown, extended downwardly away from the shoulder 9 to a greater extent than they extend upwardly toward the shoulder 9 so that the base flange 12 can lie closely against the front of the socket without interfering with tipping movement of the stud relative to the socket when it is desired to remove the stud from the socket. The latter operation is very easily performed by grasping the edge of the curtain 7 below the stud and giving it a sharp outward and upward pull which causes the stud to rock about the shoulder 9, compressing the resilient aw 10, until the stud can be removed from the socket by an unbuttoning action which permits the shoulder 9 to slip out of the socket.

The present disclosure differs from that of Serial N 0. 204,252 in that the stud is proportioned substantially to fill the socket at the top and bottom so that any upward strain on the curtain is taken directly on the unyielding portion of the stud and socket instead of on the spring, the latter serving to press and hold the stud and socket relatively in engaged position.

\Vhile I have shown and described one embodiment of my invention, it will be understood that changes involving omission, alteration, substitution and reversal of parts, and even changes in the mode of operation, may be made without departing from the scope of my invention, which is best defined in the following claims.

Claims:

1. A stud and socket fastener comprising, in combination, a socket having an aperture therein, and a stud having a shell providing a fixed abrupt shoulder for engagement with one side of the aperture in the socket, an aperture in said shell and a rounded resilient element projecting through said aperture for engagement with the opposite side of the aperture in said socket, said resilient element pressing said abrupt shoulder into engagement with the opposite side of said socket.

2. A stud and socket fastener comprising,

' in combination, a socket having an aperture therein, and a stud having a head and a neck, one side of said neck providing an abrupt shoulder for engagement with the socket, said head having a slot therein and a resilient jaw element extending through said slot for engagement with the opposite side of the aperture in the socket from said abrupt shoulder.

3. A stud and socket fastener comprising, in combination, a socket, a stud for engagement with said socket separable from said socket by tipping movement in one direction only, said stud havinga shell providing an unyielding relatively abrupt socket-engaging portion at one side thereof and carrying a yielding rounded socket-engagingelement projecting through an aperture therein for holding said unyielding shoulder in engagement with the socket.

4. A stud and socket fastener comprising,

in combination, a socket having an aperture therein, and a stud having a shell presenting an unyielding socket-engaging element at one side thereof and a yielding socket-engaging element at an opposed portion there of, said yielding socket-engaging element being formed of a piece of wire bent around the base flange of said stud.

5. A stud and socket fastener comprising, in combination, a socket having a substantially round aperture therein, said aperture having unyielding walls, and a stud for entrance in said aperture and engaging said socket, said stud comprising a shell separable from said socket by tipping movement in one direction only, and presentinga yielding socket-engaging element yieldingly opposing separation of said stud and socket by tipping movement in that one direction.

6. A stud and socket fastener comprising, in combination, a socket having an aperture therein, and a stud having a shell providing a fixed relatively abrupt shoulder for engagement with one side of the aperture in the socket, an aperture in said shell, and a sloping resilient element projecting through said aperture for engagement with the opposite side of the aperture in said socket, said resilient element pressing said relatively abrupt shoulder into engagement with the opposite side of said socket.

7. A stud and socket fastener comprising, in combination, an apertured socket and a stud having a head provided at one side withv a substantially rigid shoulder for engagement with the margin of the aperture and having a slot opposite said shoulder, an element projecting through the slot and providing a shoulder for engagement with the margin of the aperture, said element being resiliently mounted for inward yielding when 'ressed radially against said margin, one 0 said shoulders being abrupt and the other inclined.
